A valve of an air break system is provided to prevent noise from occurring due to the rapid flow of air when operating a brake. A valve of an air break system includes a cover(10'), a valve body(10), and a diaphragm(13). The cover has a first supply port(11). The valve body includes a second supply port(12) and an exhaust port(15). The supply port receives an operational air of a brake from the first supply port when coupling with the cover. The diaphragm controls the supply flow and the exhaust flow of an operational air in a coupling part of the valve body. A plurality of protrusions(13a) are formed on the upper surface of the diaphragm. The protrusion has a circular shape. The protrusions are in the line contact with inner sectional surfaces of the cover. |
